42.7. Compatibility with Other IPSec Peers

IPSec is standardized and the Intra2net system can establish connections with all standard compliant peers. However, the IPSec standard allows a wide selection of functions, some of which have to be configured or implemented identically on both sides. Therefore, we cannot guarantee overall compatibility.

Many basic devices (e.g. small routers) only support authentication with pre-shared keys. Due to the limitations described in the previous section, we can only advise doing so if both sides have static IP addresses.

If no static IP addresses are available, a router that supports Public Key should be used. The configuration of some of these routers is described in the following chapters.
